CMP Hi-Temp Union 1.5 in MIP x 1.5 in Socket 21063-150-000

CMP Hi-Temp Union 1.5 in MIP x 1.5 in Socket 21063-150-000

The right union for a pump port: this CMP hi-temp self-sealing union threads its 1.5 in male end straight into the pump's female port and self-seals on its T-gasket — no Teflon tape, no pipe dope, no callbacks. The Noryl hi-temp body (the same material family as pump housings) shrugs off heater-side temperatures that soften ordinary PVC unions.

🚩 PRO TIP: The smooth tailpiece does double duty — 1.5 in pipe glues inside it, and 2 in pipe or a 2 in fitting slips over the outside. That is why this one union covers most pump-port retrofits.

FREQUENTLY ASKED QUESTIONS:

• Do I need Teflon tape on the threads? No. The union self-seals on its gasket/O-ring — tape and dope are not required and can interfere with the seal.
• Why hi-temp? Standard PVC unions soften and distort near heaters and spa pumps. The Noryl body holds its shape and seal at equipment temperatures.
• Which end goes into the pump? The 1.5 in male threaded end. The socket end glues to your 1.5 in line (or slips inside a 2 in fitting).
